The aim of this research was to find the safety level of consuming kebab meat in the University of Muhammadiyah Malang campus area in terms of the number of microbial total plate count, Salmonella, E. coli, and S. aureus. The research was conducted with 2 treatments and 2 replications. The first observation was done during the outlet opening time and the second observation was around 8 hours after or when the outlet was going to be closed. Each treatment was sampled at 4 kebab outlets with different brands in the UMM area, so the total was 16 samples for laboratory analysis. The sample is directly pack in sterile bag, labeled sample code and bring them to the laboratory. The sample was taken to microbiology analysis in laboratory. The result showed the number of bacteria of 2 outlets with contamination levels exceeding the maximum limit set by Indonesia National Standards (SNI). The highest total bacteria count is owned by 4 th outlet which is 2. 2×10 5 ± 0. 85×10 5 CFU/g (daytime) and 4 4. 3×10 5 ± 2. 97×10 5 CFU/g (night). The lowest Total bacteria is owned by 1 st outlet, neither daytime nor evening bacterial colonies are found. Identification Salmonella, E. coli, and Staphylococcus aureus for all outlets are negative. The conclusion of this study is that two of the four kebab outlets in the UMM area was detected the bacteria total counts above of the contamination limit set by SNI 7388: 2009 and all of kebab's meat were negative identified or did not contain E. coli, Staphylococcus aureus, and Salmonella.

The influence of different feeding times forage and concentrate based on day in milk on the production and density of PFH (Friess Holland's) cow's milk. The materials used were PFH cattle aged 3 years, 2nd lactation period, elephant grass (Penicetum purpureum CV. Hamill), odot grass (Penicetum purpureum CV. Mott), Dairy cow concentrate A20. The experimental method was randomized block design (RBD). Then proceed with the Least Significant Difference Test (LSD) if the results have a real or very real effect. Feeding time was divided into P1 = Giving concentrate then giving forage after 1 hour, P2 = giving forage then giving concentrate after 1 hour, P3 = giving forage and concentrate simultaneously. The group division in this study was divided into 3 groups based on the month of lactation where K1 = 3-4 months, K2 = 5-6 months, and K3 = 7 months. The results of treatment based on data analysis based on analysis of variety showed a significant effect (P <0,05) between forage-concentrate feeding time based on day in milk on milk production. Meanwhile, the difference in forage-concentrate feeding time based on day in milk had no significant effect on specific gravity (P> 0,05). The average value of milk production from each treatment for 10 days P1 = 759.17a liter, P2 = 724a liter, P3 = 833.50b liter. The average value of milk production from each group for 10 days K1 = 1,012 liters, K2 = 820 liters, K3 = 506 liters from 21 PFH cows. The average density value of milk from each treatment for 10 days P1 = 1,0237 gr / ml, P2 = 1,0237 gr / ml, P3 = 1,0243 gr / ml. The average density value of milk from each group for 10 days from 21 PFH K1, K2 and K3 cows showed the same value, namely 1.024 g / ml. It was concluded that there was a significant difference in feeding time forage and concentrate on milk production. With the best treatment P3 which is the provision of forage and concentrate simultaneously.
